Data Format

queries.jsonl

Each line is a JSON object representing one query:

{
    "query_id": "1",
    "user_id": "10287726@N02",
    "query": "Find photos from the musical performance identified by the blue and white event logo on site, where only the lead singer appears on stage.",
    "answer": ["7759256930", "7759407170", "7759295108", "7759433016"],
    "event_type": "intra-event"
}

Field	Type	Description
query_id	string	Unique query identifier
user_id	string	User whose photo collection to search
query	string	Natural language query (text-only)
answer	list[string]	Ground-truth target photo IDs
event_type	string	"intra-event" or "inter-event"

metadata/{user_id}.jsonl

Each line is a JSON object representing one photo's metadata:

{
    "photo_id": "4517621778",
    "metadata": {
        "taken_time": "2010-04-10 13:52:57",
        "longitude": -1.239802,
        "latitude": 51.754123,
        "accuracy": 16.0,
        "address": "Y, Cherwell Street, St Clement's, East Oxford, Oxford, Oxfordshire, England, OX4 1BQ, United Kingdom",
        "capturedevice": "Panasonic DMC-TZ5"
    }
}

Field	Type	Description
photo_id	string	Unique photo identifier
metadata.taken_time	string	Capture time in YY-MM-DD HH:MM:SS format
metadata.longitude	float	GPS longitude. Missing if unavailable.
metadata.latitude	float	GPS latitude. Missing if unavailable.
metadata.accuracy	float	GPS accuracy level. Missing if unavailable.
metadata.address	string	Reverse-geocoded address. Missing if unavailable.
metadata.capturedevice	string	Camera/device name. Missing if unavailable.

Note: Optional fields (longitude, latitude, accuracy, address, capturedevice) are omitted entirely when unavailable — they will not appear as keys in the JSON object.

images/{user_id}/{photo_id}.jpg

Photo files organized by user. Each user's collection contains approximately 2,000 photos accumulated chronologically from their photosets.

photo_ids/{user_id}.txt

Each line represents one photo ID and its hash on aws storage in the format {photo_id}\t{hash}:

1205732595	c45044fd7b5c9450b2a11adc6b42d

Field	Type	Description
photo_id	string	Unique photo identifier
hash	string	Hashed value of the photo on aws storage
